 documentation of libsoni is publicly accessible through GitHub[^1]. Furthermore, the applications of core
 functionalities are illustrated by educational Jupyter notebooks as an integral part of libsoni, providing 
 illustrative code examples within concrete MIR scenarios.

 ## Piano-Roll Representations (\texttt{libsoni.pianoroll})
 A symbolic score-based representation describes each note by parameters such as start time, duration, pitch, and other 
 attributes. This representation is closely related to MIDI encodings and is often visualized in the form of 
-two-dimensional piano-roll representations (see also Figure \autoref{libsoni}c). In these representations, time is
